I have a 190 lph fuel pump in my sc'ed gsr hatch. The tune I am running is set up for stock fuel pressure, which is like 46 psi or something. My car has been running like shit because the fuel pressure is like 64 psi. I have an oem FPR. I replaced it once again with a unit from the junk yard and it is still getting way too much pressure. Are the oem fpr's garbage when you have a fuel pump putting out alot more volume, or is it just bad luck with fpr's? I'd hate to spend the money on an adjustable unit.
